This invention `relates to coilersfiof the type used text-ile Amills to `coil'the sliver into. a can immediately yafter Athe sliver comes A coiler includes a bar, commonly called a tongue, which is provided .with a tapered hole, known as a trumpet, throu h which the roving'is guided tothe feed ro ls ofthecoiling meclninism.` Thistongue 1s pivoted at thebaek of the ineojhanism and `fromacardiug machine.

`fits in 'a slot formed 1in the cover vor bonnet of the machine. The `tongue and bonnet should fit together tightly without vleaving any open crack or crease between them, and `for this' reason :each tongue must betted to the yparticular bonnet with which it is to be used. The upper surface'of the tongue is made level with the corresponding sur.- face of the bonnet and 'both surfaces are pols ished forming, in effect, a continuous sur# face. This construction not only is relatively eX- pensive tomanufacture, but it is a particularly expensivefmatter to replace a broken tongue. Oftentimes it is necessary to send a machinist to the mill in `which the broken coiler is installed to replace the tongue and fit it properly into the bonnet. It is the chief object of the present invention to overcome this difficulty. That is, the invention aims to devise a construction in which ythe tongues will be interchangeable so that any special fitting of an individual tongue toa bonnetlwill lbe eliminated. It is also an objcct'm the invention to facilitate the inspection of the machine during operation.

The nature of the invention will be readily following description when read in connection `with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims. y

Referring now to the drawings,

Figure 1 is a plan view of a coiler with certain parts of the bonnet broken away;

Fig. 2 is a vertical cross sectional kview through the upper part of the coiler shown in Fig. 1; and

Fig. 3 is a perspective view of a part of the tongue provided by this invention.

The machine shown includes a vertical shaft 2 carrying a pinion 3 which drives a gear 4 formed lntegral with the coiler tube I 5. Secured on the `upper end of theshaft 2 isya bevel gear 6 drivinanother Abevelfgear which is fast on the feed `roll shaft 8. A pinion 9 integral `with the 'bevel gear "7 drives .the other feed roll shaft. areindicated at 1() and 12, respectively.

The tongue 14 `.is pivoted at 1 5 between the ears of abracliet 16, and `itis provided with a trumpet 17 to guide the roving or .sliver R `downwardly between the feed rolls `10 and 12. This tongue is vnormally he"1d"`in its fop- `erative position yby gravity, `the forward end of thef'tongue beingweli-ghfted "or thiekened, as shown at 18. It is provided on its lower `surface roll shafts. i i

VThe bonnet 21 is piwotod tothe rem-off the :machine at 22. `This bonnet, unlike the usual constructions, slot -23 `extending from front to rear, and the metal of the bonnet surrounding the slot is turned downwardly, as clearly shown alt 24 in Fig. 2, and rests on the tongue 14. The upper surfaces of both the tongue and the bonnet are polished, and the tongue has a flat top on which the lower flat edge of the rim 24 rests, forming a comparatively tight joint between these parts.

The slot in the bonnet is made so long that the bonnet can be tipped backwardly into its inoperative position, as indicated by dotted lines in Fig. 2, without interfering with the feeding movement of the roving. or sliver, the sliver simply taking a somewhat different path atthe back of the machine, as indicated at R. This is an important advantage in permitting the operator to inspect the action of the machine without interrupting its* operation.

` In order to enable the workman to observe thc feeding of the sliver between the trumpet and the feed rolls, I have disposed the weighted or enlarged portion 18 at the forward end of the tongue chiefly on one slde ofthe median line of the tongue, thus leaving a space between the part 18 and the foot y20, as shown in Fig. 1, through vwhich the operator can see the lower end- `of the trumpet 17 when the bonnet is lifted Serenna mo :saco-` A GoRroRATIoN on `massacran- The two feed rolls is "provided with av '110mg i Due to the fact that the bonnet simply rests on the tongue Without fitting around it, as in prior' constructions, the tongues can all be made alike so that they are interchangeable. This is an important advantage in manufacture and itis an even greater advantage in replacing broken tongues, since it eliminates any necessity for fitting a tongue to an individual bonnet, as has been required heretofore. The weighting of the end of the tongue also does away with the spring latch that has been used heretofore to hold the tongue in its operative position.

While I have herein shown and described the best embodiment of my invention that I have so far devised, it is contemplated that minor modifications may be made without departing from the spirit or scope of the invention.

HavingV thus described my invention, what I deslre to claim as new is: e

1. vIn a coiler, the combination of coilmg mechanism, a tongue having a trumpet for guiding a sliver to said mechanism, and a bonnet for protecting said mechanism, said bonnet overlying said tongue and having a long slot therethrough extending from front to rear and closed by said tongue, said slot being suiciently long to allow the bonnet to be tipped into its backward position Without interfering with the feeding of i the sliver.

2.4 In a coiler, the combination of coiling mechanism, a tongue having a trumpet for guiding a sliver to said mechanism, and a bonnet resting on said tongue, said tongue having a smooth flat upper surface, and said bonnet having a slotted portion ,surrounded by a smooth lower `face to bear onthe upper surface of said tongue.

3. In a coiler, the combination of coiling mechanism, a pivoted tongue having a trumpet for guidin the sliver to said mechanism, the forwar end of said tongue being weighted, and a bonnet pivoted at the back of the machine and havin a long slot therethrough extending from ront to rear with the lower face of said tongue around said slot resting on said tongue.

4. In a coiler, the combination of coiling mechanism, and a pivoted tongue having a trumpet for guiding the sliver to said mechanism, the forward end of said tongue being weighted, with the weighted portion disposed chieiiy at one side of the median line of the tongue so that a view of the trumpet is afforded under the end of the tongue and past said weighted portion.

5. .In a coiler, the combination of coiling mechanism, a tongue having a trumpet for guiding the sliver to said mechanism, and la bonnet overlying said tongue and mounted to swing upwardly away from the tongue,
